Why Wont It All Work

Sorry to bring this back in again but I have been trying for weeks to get this to all come together.

Layout - I have a modem/router (supplied by my ISP - Alice here in France). It has both Ethernet and WiFi capabilities with the WiFi set up via a PCMCIA card into the modem router. Link will take you to a French site but you'll be able to see the layout.

From the M/Router - I have 3 PC systems connected by cabled method - all work great and see each other and the Internet Connection on each is very good.

Elsewhere - I have 2 PC's which have PCI WiFi cards. They are able to see each other but not the network.

The M/Router has an IP of 192.168.1.1 and this is the range I have used for the 3 PC's connected by cable.

The strange thing is that the PCMCIA card in the M/Router shows an IP of 192.168.3.1. I have pinged the 3 pc's and the PCMCIA card and the M/Router and they all deliver spot on returns.

The 2 PC's with the PCI WiFi just will not see the M/Router or the network. They show connected in the sys tray but they do not see the network. I have tried to use the Gateway as both 192.168.1.1 and the 192.168.3.1 IP addresses.

The 2 PCI WiFi cards are set up with no encryption, on an open basis and Ad-Hoc. The Profiles are the same on each and the IP addresses are Manually Configured.

No matter what I do I cannot get the 2 PCI WiFi systems to get onto the network. Any ideas would be very gratefully received.

Maybe it is an MTU problem. Try to find a setting in the router for MTU and change it to 1,000 ... if it works then increase it to 1,400 and leave it at that if it works. Beyond that a search in google indicates Tiscali also supply this modem including this page click here otherwise search google for

HI - DHCP was used but I manually assigned as I have been trying different IPs. have pinged all machines, including the router and PCMCIA (which is on the 192.168.3.1 range) and they have all pinged perfectly except the 2 systems with the PCI cards installed.

Sorry - but you have lost me with MTU. What is this and where would I find it.

As I don't know your router, I can't tell you where exactly (Maybe in WAN settings) but if you log into the router interface you'll have to look around to find the MTU (It's probably set to 1500 at the minute).

If it's not that I think it might be the PCMCIA having IP address 192.168.3.? and not 192.168.1.?
